Surely many prescribed analysis on RW.What it is?This abbreviation stands for the reaction Wasserman, a study is conducted to diagnose syphilis.This method belongs to the category of screening, that is aimed at early detection of disease in asymptomatic patients.This type of diagnosis is often used in mass screening.

It should be mentioned that the results of that analysis shows RW, can not be considered guaranteed.Thus, the positive or negative response is not yet evidence of the presence or absence of the pathogen in the body of syphilis - Treponema pallidum.Thus, analysis RW - is indicative method, which, however, reveals the disease at an early stage.Accurate diagnosis of syphilis is performed by specific (treponemal) methods.

If a negative result of the analysis, it may indicate how the absence of disease, and that it is still in the initial stage, or alternatively, at a later, tertiary.That is, in the first two to three weeks after infection, the reaction may be negative.

positive result is not always indicative of infection treponemoy.In medicine, there is such a thing as a false positive reaction, which may be associated with a number of diseases: viral hepatitis, cancer, tuberculosis, drug addiction and diabetes.In addition, a "response" of the body is possible during pregnancy, post-vaccination and with the use of a number of blood before taking the food.

Wasserman is the first and easiest method of detection by the disease.Analysis RW is collecting venous blood glucose.Syphilis, as already mentioned, is a spiral-shaped bacterium - pale treponema (spirochete).Outside the human body, it is able to live up to 4 days, which explains the risk of infection asexual.

This analysis is based on the fact that in healthy individuals in the blood process of hemolysis (destruction of red blood cells), which is absent in patients.There are two primary stage of syphilis: seronegative (RW negative, requires other research methods) and seropositive, which can have varying degrees of reaction: ++, +, and - mild, +++, - positive, ++++ - rezkopolozhitelnaya.Typically, most cases of syphilis are positive only after 7 weeks.
